ps4 syscon help #1
Description
hi my friend.
I have been working on an STM32 programmer for the PS4 RL78 Syscon that can read, write, and enable debug mode. There are projects on this subject, but they are not open source hardware, and there is no information available on how to write to the Syscon.
Maybe using shellcode to activate OCD after glitching it, and then using OCD to read and write? Or is it just for debugging, and the shellcode is the way to go?
No one is willing to provide answers, and I couldn't contact you on Twitter, so I opened this issue to seek your help. Please help.
Right now, I am using an FM33LC023U, a Cortex-M0 with USB CDC VCP capability and 4 UART interfaces.
Can you provide me with working shellcode or arduino code or guidance on the approach? I am stuck and need your help.
The glitching and read process is known and described, but there is no information about writing.
thanks.
